How to Replace Cartridge(s)

Here's the fast and easy way to replace the toner cartridge in your Brother MFC-8520DN laser printer:

  1. Leave the machine turned on for a few minutes to give it time to cool its internal parts. Once it's fine, press the front cover release button and open the front cover.
  2. Remove the drum unit and toner cartridge assembly. Set it down on a drop cloth to avoid spills, then push down the lock lever. This releases the used toner cartridge, allowing you to take it out of the drum unit.
  3. Unpack the new toner cartridge. Hold it level with both hands and shake it gently several times to distribute the toner evenly inside. After this, pull off the protective cover.
  4. Insert the new toner cartridge into the drum unit until it locks into place. Then, clean the primary corona wire of the drum unit.
  5. Reinstall the drum unit and toner cartridge assembly into the printer.
  6. Close the front cover.
